RecepTrexx LLC v. ALE USA Inc. — Voluntary Dismissal After 89 Days
RecepTrexx LLC filed suit against ALE USA Inc. in the District of Delaware asserting reissue patent USRE042997E, which covers triggered playback of recorded messages to incoming cellular telephone calls. The action was voluntarily dismissed without prejudice under FRCP 41(a)(1)(A)(i) before ALE USA filed any responsive pleading — just 89 days after the complaint was filed.
Pre-answer dismissal signals unresolved leverage in cellular messaging IP
RecepTrexx LLC filed this patent infringement action on 2 February 2024 in the United States District Court for the District of Delaware, asserting reissue patent USRE042997E against ALE USA Inc., the US arm of the enterprise communications group formerly operating under the Alcatel-Lucent Enterprise brand. The patent in suit covers triggered playback of recorded messages to incoming telephone calls directed to a cellular phone — a function relevant to enterprise telephony, auto-attendant, and unified communications platforms.
The case closed on 1 May 2024, just 89 days after filing, when RecepTrexx invoked Federal Rule of Civil Procedure 41(a)(1)(A)(i) to dismiss the action voluntarily. The notice was filed before ALE USA had answered the complaint or moved for summary judgment, which is the procedural threshold that permits a plaintiff to dismiss as of right — without court approval and without prejudice. The public record does not specify whether the dismissal followed a settlement, licensing negotiation, or a unilateral tactical decision.
The brevity of the dispute — 89 days from filing to closure — is consistent with either an early licensing resolution or a strategic withdrawal to re-evaluate or refile. Because the dismissal was without prejudice, RecepTrexx retains the right to reassert USRE042997E against ALE USA in the future, subject to applicable statutes of limitations. The absence of any defendant law firm entry on record suggests ALE USA may not have formally engaged outside counsel before the dismissal occurred, which further compresses the publicly available record.

Voluntarily dismissed: what the without-prejudice distinction means here
FRCP 41(a)(1)(A)(i): dismissal as of right, no court order needed
Under Rule 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves either an answer or a motion for summary judgment. The dismissal takes effect immediately upon filing. Because ALE USA had not yet answered, RecepTrexx could exit the litigation unilaterally. This procedural posture means the merits of the patent infringement claim were never tested or adjudicated.
Pre-answer dismissalThe public record is silent on whether this reflects a deal
A dismissal without prejudice means the plaintiff may refile the same claim in the future, whereas a dismissal with prejudice would permanently bar reassertion. RecepTrexx explicitly chose the without-prejudice formulation. However, the public record does not disclose whether this followed a confidential settlement, a licensing agreement, or a purely tactical withdrawal. Practitioners should treat the distinction as legally significant but commercially ambiguous based on available filings.
Refiling remains possibleRecepTrexx retains all rights to reassert USRE042997E
RecepTrexx exits this action with patent rights intact and no adverse judgment on record. A without-prejudice dismissal preserves its ability to re-engage ALE USA or pursue other alleged infringers under USRE042997E. If a confidential licence or payment was secured, the litigation served its commercial purpose. If not, the patent remains a live enforcement asset that could be deployed again — against this defendant or others in the enterprise telephony space.
Patent enforcement rights preservedALE USA faces no injunction or damages — but no invalidity ruling either
ALE USA obtains an immediate end to this specific proceeding without incurring a damages award, injunction, or any finding of infringement. However, because the case ended before any substantive proceedings, ALE USA also secured no invalidity or non-infringement ruling that could shield it from a future action under the same patent. The without-prejudice character of the dismissal means potential exposure to USRE042997E persists unless a licence or covenant not to sue was privately negotiated.

Official order — verbatim text
The dismissal notice invokes FRCP 41(a)(1)(A)(i) in precise terms, confirming the procedural basis — plaintiff’s right of dismissal before any responsive pleading. The explicit notation that ALE USA ‘has not yet answered the Complaint or moved for summary judgment’ is a deliberate record-preservation statement, establishing the procedural threshold was met. No merits were reached. The without-prejudice designation is the most commercially significant element: it leaves the litigation door open and USRE042997E fully enforceable against this and other defendants.
USRE042997E — Triggered Playback of Recorded Messages to Cellular Calls
USRE042997E is a United States reissue patent — meaning its claims were revised and reissued by the USPTO after the original grant, typically to broaden or correct the scope of protection. The patent covers triggered playback of recorded messages to incoming telephone calls directed to a cellular phone. This technology is foundational to enterprise auto-attendant systems, interactive voice response platforms, voicemail greetings, and any cellular or VoIP product that intercepts or responds to an incoming call with pre-recorded audio content.
For enterprise communications vendors — including those offering PBX, UCaaS, or hosted telephony products — this patent represents a meaningful infringement vector. Reissue patents are strategically valuable enforcement tools: the reissue process is specifically intended to ensure claims cover real-world products, and courts have historically given reissued claims significant weight. ALE USA’s product lines, which span enterprise IP telephony, hotel communications, and cloud PBX, sit squarely within the functional scope this patent purports to cover.
Should your product team run an FTO against USRE042997E?
Any R&D team developing auto-attendant, IVR, voicemail, call routing, or message-triggered playback features for cellular or VoIP platforms should treat USRE042997E as a priority freedom-to-operate target. The patent’s reissue status means its claims were purposefully calibrated to capture commercial products, and the fact that it has already been asserted in litigation — and resolved without a validity or non-infringement ruling — means it remains an active enforcement risk. UCaaS vendors, enterprise PBX developers, and hosted telephony providers are particularly exposed.
PatSnap Eureka’s FTO Search Agent allows product and IP teams to map the claims of USRE042997E against specific product features in minutes, identify potential design-arounds, and surface prosecution history estoppel arguments from the reissue file wrapper. Running a targeted FTO now — before a demand letter arrives — is materially less expensive than litigation defence in Delaware. Eureka can also flag any continuation or related applications that may extend the patent family’s enforcement reach.

What this case signals for the enterprise telephony IP landscape
Short-duration, pre-answer dismissals in Delaware patent actions often indicate early commercial resolution — or strategic repositioning before a broader campaign.
Pre-answer dismissals in Delaware patent cases warrant close monitoring
When a patent plaintiff dismisses voluntarily before the defendant even answers, it typically signals either a rapid licensing resolution or a tactical pause. For competitors and partners of ALE USA operating in the enterprise unified communications space, this case is a prompt to audit exposure to USRE042997E — particularly for products involving auto-attendant, call routing, or triggered message playback features.
Reissue patents carry broader claim scope — due diligence is non-negotiable
USRE042997E is a reissue patent, meaning its claims were deliberately broadened or corrected after original grant. Reissue patents can present higher infringement risk than the original because amended claims are specifically designed to capture commercial embodiments. Any company developing or selling cellular or VoIP auto-response, voicemail, or message-triggered playback functionality should verify clearance against this patent’s current claim set.
RecepTrexx v ALE — key questions answered
The dismissal was filed without prejudice under FRCP 41(a)(1)(A)(i), meaning no merits ruling was issued and RecepTrexx retains the right to refile against ALE USA or assert the patent against other defendants. The patent remains fully enforceable.
The public record does not confirm a settlement. The voluntary dismissal notice references only the procedural basis — FRCP 41(a)(1)(A)(i) — and does not disclose any financial terms or licence agreement. A confidential resolution cannot be ruled out but cannot be confirmed from available filings.
USRE042997E covers triggered playback of recorded messages to incoming telephone calls directed to a cellular phone. As a reissue patent, its claims were deliberately revised post-grant to broaden or correct scope. Enterprise telephony vendors with auto-attendant, IVR, or voicemail features are within the potential infringement perimeter.
Delaware is a favoured jurisdiction for patent plaintiffs due to its sophisticated judiciary, experienced bench, and well-developed patent case law. ALE USA Inc. is incorporated or registered in Delaware, establishing clear personal jurisdiction. The district’s predictable procedures also support early case management and pre-trial resolution.
Yes. A without-prejudice dismissal under FRCP 41(a)(1)(A)(i) does not bar refiling. RecepTrexx may reassert USRE042997E against ALE USA in a future action, subject to any applicable statute of limitations and any private agreement reached between the parties. ALE USA holds no invalidity or non-infringement ruling from this proceeding.
